Watered once this week as the soil meter was indicating its still moist and the upper part of the medium was sprayed with a water few time a day to increase humidify level.
My tap water has quite high PH level (around 7,5-8) hence I've used PH down and adjusted it to 6 PH.
Growth was a bit slow due to incorrect light distance and power level used.
LED high was adjusted to 60 cm and power was dimmed to 30%.
